Title: Improvements in train control and cab signalling apparatus actuated inductively from the track
IPC: B61L3/12
Filed: 1947-06-21
Abstract: 668,264. Track apparatus for actuating signals on and controlling trains. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE, SOC. ANON. STIN. June 21, 1947. [Dec. 26, 1946] No. 16462/47. Class 105. In an inductive system for transmitting to a train an indication of the wayside signal setting by means of a pair of track cores 5, 6 the windings of which are series completed only if the wayside signal is at the clear aspect whereby a direct-current magnet 4 on the train can induce a current pulse in the winding of one track core 5 to energize the other core 6 which in turn gives a pulse to a winding of a receiver core 7 on the train, there is provided a track magnet 8 independent of the pair of track cores 5, 6 and actuating the receiver 7 and thus at a wayside signal at clear two pulses are given to the receiver. Alternatively, an additional inductive system may be used to give the second pulse. A defect in the windings of the track cores 5, 6 causes only one pulse to be given and this is arranged to give a warning signal on the train. Receipt of the second pulse prevents the first pulse putting the warning signal into operation.

Abstract: 515,539. Hook fastenings; slidable bracket hinges. AUSTIN MOTOR CO.. Ltd., and LORD. L. P. June 3, 1938, No. 16617. [Classes 44 and 65 (ii)] [Also in Group XXXI] In a motor vehicle bonnet of the kind having a single top flap adapted to be raised about a rear transverse hinge, the hinging means is raised bodily prior to lifting of the flap in order to provide clearance between the rear edge of the flap and the scuttle dash or equivalent body part which carries the hinges. Preferably, the means for raising the hinges also releases the catch normally securing the front of the flap. The rear corners of the top flap G are pivoted on the upper bent ends e<2> of rods E slidably mounted in brackets F secured to the scuttle partition B. The lower bent ends e of the rods, drawn down by springs e<3>, rest on the cranked ends a' of a transverse shaft A mounted in bearing brackets b, also secured to the partition B. The cranked ends a<1> normally lie in a horizontal plane, and, in a plane inclined thereto, the middle part of the shaft A is cranked at a, a connecting rod c leading therefrom to a disc c rotatably mounted on a stud c<2> adjustably secured in a partition board D and provided with a handle c<3>, the shaft A thus being given a part rotation to raise the hinges. A hook K, normally engaging an inverted U-bolt p to secure the front end of the flap, may also be released by connection thereof by a link M to a lever H pivoted in a bracket J. on the partition B, the crank a, or, if desired, another cranked part of the shaft A, passing through a slot h in the lower end of the lever. The lower end of the slot h may be concentric with the shaft A so that the catch is not released until the hinges have been partly raised. The hinges may be operated so as to raise the rear end of the bonnet, keeping the front end fastened, when driving under snowy, frosty or like weather conditions. The Provisional Specification describes an arrangement wherein the operating disc C is carried by a vertical partition.

Abstract: 758,404. Turning-gear. DAIMLER-BENZ AKT.-GES. June 11, 1954 [Jan. 18, 1953], No. 17266/54. Class 7(5) [Also in Group XXIX] Construction: In a pressure liquid or gas installation comprising a main enginedriven pump 14 supplying auxiliary appliances, such as rams 43, and an auxiliary pump 45 driven independently of the engine for taking over the supply duty when the engine is at rest and during starting periods, a disengageable driving connection 12 between the engine and the main pump 14, and control means, such as a changeover valve 29 and a pressure regulating valve 53, the auxiliary pump 45 supplies pressure fluid to the main pump 14 so that the latter acts as a motor to drive the engine through a pinion 25 and a gear 26 on the engine shaft when it is desired to start the engine. On the shaft 13, of the swashplate pump 14 (see also Group XXIX) normally driven from the engine through a belt 11 and the free wheel 12, is arranged a slidable but non-rotatable sleeve 20 which has a flange adapted to work as a piston in a cylinder 21 and which is urged leftwardly by a spring 23. The sleeve 20 is connected by free wheel 24 to the pinion 25. Starting: A starter switch 67 is operated with or after closure of the ignition switch 48 so that the auxiliary electrically-driven pump 45 draws fluid, preferably oil, from a reservoir 27 and supplies it to the main pump 14 which is then driven as a motor, and to the cylinder 21 to engage the pinion 25 with the gear 26 and effect cranking of the engine. As the speed of rotation increases the stroke of the pump 14 is varied to maintain a constant starting power. When the engine starts, the switch 67 is opened and the main pump 14 then performs its normal function; upon the pressure in the system attaining a given value the auxiliary pump is automatically stopped. The auxiliary pump may be manually or otherwise operated. Specification 758,384 [Group XXVIII] is referred to.
